Felipe received a $15.25 gift card for a photo center. He used it to buy prints that cost 6 cents each. The remaining balance, B (in dollars), on the card after
buying x prints is given by the following
B = 15.25 -0.06x
What is the remaining balance on the card if Felipe bought 50 prints?
Can anyone help me ?
Answer:
12.25
Step-by-step explanation:
B = 15.25 -0.06x
B = 15.25 -0.06(50)
B = 12.25
Factor the expression 4+28x using the GCF
Answer:
4(1+7x)
Step-by-step explanation:
There are 2 terms in this expression: Factorize them
4: 2 * 2
28x: 2 * 2 * 7 * [tex]x[/tex]
Which factors do both of the terms have in common?
2 and 2, which means that the GCF is 4.
Now to figure out whats inside the parentheses.
What number multiplied by 4 gives 4? 1
What number multiplied by 28x gives 4? 7x
So the final result is 4(1+7x)
find the area of the composite figure
Answer:
74 in²
Step-by-step explanation:
The easiest way to find the area is to imagine the rectangle as a whole rectangle, then subtract the area of the empty space.
The area of the whole rectangle can be found with:
A = b · h
A = 9 in · 11 in
A = 99 in²
So the area of the entire rectangle (with the empty space included) is 99 in².
In order to find the area of the composite figure, you need to subtract the area of the empty space, which can be found with:
A = b · h
A = 5 in · h
In order to find the height of the empty space, we can take the whole side (11 in) and subtract the values already there (4 in and 2 in).
11 in - (4 in + 2 in) = 5 in
So the height is 5 in:
A = 5 in · 5 in
A = 25 in²
The area of the composite figure is:
A = 99 in² - 25 in²
A = 74 in²

Answer:

Step-by-step explanation:
Perimeter of parallelogram = 70 ft
-> 2x + 2y = 70 .....(1)
x = 6y (Given) .....(2)
From equations (1) & (2)
2(6y) + 2y = 70
12y + 2y = 70
14y = 70
y = 70/14
y = 5
-> x = 6*5
-> x =30
This shape is called parallelogram.
perimeter : 2(base + height)
Identify the base and height
base : x ≈ 6(y) [ as x is 6 times as large as y ]
height : y
====================================
2(base + height) = perimeter2(6(y) + y) = 70 2(7y) = 707y = 35 [ divide both sides by 7 ]y = 5Find x:

Molique is taking a road trip every time he stops for gas he records the number of miles he has driven and the number of gallons of gasoline his car has used the number of miles Millie drives is proportional to the number of gallons of gasoline his car uses how fill in the missing values in the table
Based on the fact that the distance driven is proportional to the gallons used, the missing figure is 8 gallons.
Why is 8 gallons the missing figure?The question is incomplete so I will use a similar question to explain the concept.
If the number of miles driven is proportional to the number of gallons used then you can find the number of miles driven per gallon as:
= Number of miles driven / Number of gallons used
= 112 / 4
= 28 miles per gallon
You can also use other entries in the table to get the same answer:
= 280 / 10 gallons
= 28 miles per gallon
If 224 miles have been driven, the number of gallons used would therefore be:
= Number of miles driven / Miles per gallon
= 224 / 28
= 8 gallons

The is a picture show all details and work
(triangles)
Answer:
x: 8.75
y: 8.5
Step-by-step explanation:
Since the two triangles are similar, you can find the scale of LJK relevant to TRS by dividing 7/4 = 1.75
This means each side of LJK is 1.75 times greater than the respective side of TRS
Now you can plug this in to the other two sides by doing 5*1.75=8.75 and 6*1.75=10.5
This solves x, but since side LK is y+2, y is 10.5-2=8.5
x=8.75
y=8.5

A class of 30 students must elect a representative to go to a local
conference. They must also elect one alternate representative, in case the
first representative becomes ill or unable to go at the last minute.
How many different ways can the class elect a representative and
a
alternate?
Answer:
870.
Step-by-step explanation:
There are 30 choices of representatives. This leaves 29 choices for alternate representatives.
If one person gets elected for representative, there are 29 choices for an alternate representative.
This is the case if any of the 30 students get elected as representatives.
That means you can set it up as:
x*y where x is the choice of representatives and y is the choice of alternate representatives.
30 * 29, or 870.
Here is a visual example. Students a - dd are shown here.
a b c d e f g h i j k l m n o p q r s t u v w x y z aa bb cc dd
In this case, a has been chosen as class president. Any of the other 29 students could be a alternate, and then paired with a. This makes 29 total possible pairings. This is then repeated for the possibility of every student becoming a president, which creates 30*29.
Please tell me if this is wrong, I will try to make changes!

Answer:
165 km²
Step-by-step explanation:
First, let us find the area of the big rectangle.
Area = length × Width
Area = 15km × 13 km
Area = 195 km²
Now, let us find the area of the small rectangle.
Area = length × width
Area = 6 km × 5 km
Area = 30 km²
And now, let us find the area of the shaded region.
For that, we have to subtract the area of the small rectangle from the area of the big rectangle.
Area = 195 km² - 30 km²
Area = 165 km²
